WE UNDERSTAND YOUR CONCERNS

Is a bathtub door worth it? Honest answers

“Do I need a complete remodel for this?”

No. Only the bathtub is modified – the rest of the bathroom remains completely untouched. Much faster and more affordable than a complete renovation.

“Won’t the water leak out?”

Absolutely not. The door is professionally sealed with silicone and, when used correctly, is 100% watertight. You can still enjoy a full bath.

“Is this possible with my bathtub?”

Yes. Whether acrylic, steel or cast iron – bazuba finds the right solution for almost every type of bathtub. Our technicians will check this free of charge on site.

“How much does it all cost?”

From around €2,900, fixed price after inspection. In many cases, funding is available that significantly reduces your own contribution.

BATH WITH DOOR

Bath with door: retrofit instead of buying new

If you are looking for a bath with a door, you have two options: buy and install a new walk-in bath, or have a door fitted into your existing bath. bazuba does the latter. The bathtub door (in Austria called Badewannentüre, often also Wannentür or Badewanneneinstieg) is in one day installed into your existing bath, From around €2,900.

Buy newWalk-in bathA completely new bath with an integrated door. The old bath must be removed, and the panelling and tiles around the bath are usually renewed as well.
Buy newSeated bath with doorA shorter, higher bath with a seat, designed for small bathrooms and for anyone who no longer wishes to bathe lying down. This also replaces the existing bath.
Retrofitting with bazubaDoor in your bathThe bath remains. We cut out the entry, fit the custom-made door and seal it. Full baths remain possible, and the rest of the bathroom is untouched.

If your bath is still in good condition, the retrofitted door is usually the quickest way to a bath with a low entry. Whether a door can also be fitted into an existing seated bath depends on its shape and material. We check this during the free inspection. You can find a detailed comparison of the three options, including costs and subsidies, in the guide Bath with door: retrofit or buy new?

As a senior bath or accessible bath, the bath with door is often combined with Anti-slip finish and grab handles. If you are unable to step over any edge or use a wheelchair, a level-access shower is a better solution: Tub out, shower in. An overview of all options is provided on the page barrier-free bathroom.
